The Original Edition: The original work was published in German by Gottlob Frege, a German mathematician, logician, and philosopher. This edition, which was later translated into English, typically consists of three volumes.
- Volume 1: “Begriffsschrift, eine der arithmetischen entwicklung fähige geschichte der mathematischen wissenschaften upon which are founded, the logic of this book”
- Volume 2: “Die Grundlagen der Arithmetik, eine logische Untersuchung”
- Volume 3: “Funktion, Begriff, Zahl”
